The drawing of Felicity in the last panel is lifted from some old promo art Meaghan drew me once upon a time for the stand-alone "Felicity" comic. In point of fact, I drew her in that outfit a few weeks ago based upon that same piece of art because I thought it looked super cute. And, to pile onto the stack of trivia, the file Meaghan sent me way back when was actually named "scusemewhileikillthisguy.jpg." Because clearly I'm not clever enough to think of that line myself.
If you wanna get really technical about it, I laid down Meaghan's original line art for panel four's Felicity in Photoshop, then inked it myself so it'd look normal next to everything else. In any event, while I'm clearly willing to cheat and steal from others (and myself), at least I'll fess up when I do.
